Article of footwear having a flexible fluid-filled chamber

摘要

An article of footwear may include an upper forming a void within the footwear, a sole structure secured to the upper, and a chamber that encloses a pressurized fluid. The sole structure includes a depression. The chamber is located within the void of the upper and located on the depression of the sole structure. The chamber may include a plurality of fluid-filled subchambers, a manifold, and a connection fluidically-connected at least one of the subchambers to the manifold. The subchambers may enclose the pressurized fluid at different pressures. The subchambers may be separated from one another by a bonded area in the direction extending between the heel and toe of the chamber.

1. An article of footwear including a heel region and a forefoot region, the article of footwear comprising:
an upper forming a first portion of a void within the footwear; a sole structure secured to the upper, the sole structure forming a second portion of the void; and a chamber that encloses a pressurized fluid and includes a longitudinal axis that extends between the heel region and the forefoot region, the chamber being located within the void and including a first plurality of fluid-filled subchambers that extend in a medial to lateral direction of the footwear along individual longitudinal axes that are perpendicular to the longitudinal axis of the chamber, and a manifold that extends continuously along one of a medial side and a lateral side of the sole structure from a first end of the chamber disposed in the heel region to a second end of the chamber disposed in the forefoot region, the manifold being in fluid communication with the first plurality of fluid-filled subchambers, and the manifold is intersected by the longitudinal axes of the first plurality of fluid-filled subchambers at a same edge of the manifold, each of the first plurality of fluid-filled subchambers being fluidly connected to the manifold by a respective individual fluid connection; wherein each respective individual fluid connection, in a direction from a toe end of the chamber toward a heel end of the chamber, is successively farther in distance from the toe end of the chamber; and wherein a cross-sectional area of each individual fluid connection is less than a cross-sectional area of the individual fluid connection's respective fluid-filled subchamber.
